The R911373654 (MSK050B-0450-NN-S2-UP1-RNNN) is a Bosch Rexroth synchronous servomotor, designed with a protection rating of IP65 and optimized for ambient temperatures from 0°C to +40°C at installation altitudes up to 1000 m above sea level. This IndraDyn S model features a natural convection cooling system, a reduced shaft with keyway, and a singleturn optical EnDat2.1 encoder with 2048 signal periods and a rotatable connector (240°). It has a winding resistance of 5.70 Ω at 20°C, winding inductivity of 33,600 mH, and a voltage constant of 73.5 V/rpm. The unit provides a continuous standstill current of 3.2 A and torque of 3.4 Nm (100 K), with a peak current capacity of 11.2 A and maximum torque of 9.0 Nm. It includes four pole pairs and an electrically-released holding brake (24 VDC, 6 Nm). The servomotor weighs 4.9 kg, uses ambient air for cooling, and is coated in prime black for resistance to dust and mild acids.

Frequently Asked Questions

How does the rated speed code 0450 affect motor functionality?

The rated speed code defines base motor speed for controlled operations. This enables optimized tuning for applications requiring specific rotational velocities.

Why is increased concentricity important in MSK050B-0450-NN-S2-UP1-RNNN motor?

The increased concentricity of MSK050B-0450-NN-S2-UP1-RNNN motor minimizes shaft runout and vibration. This ensures longer bearing life and smoother machine integration.

How does the EnDat2.1 encoder in MSK050B-0450-NN-S2-UP1-RNNN motor benefit automation systems?

The EnDat2.1 interface of MSK050B-0450-NN-S2-UP1-RNNN motor enables high-resolution feedback and error diagnostics. This supports precise synchronization in multi-axis setups.

Why is 11.2 A maximum current significant in MSK050B-0450-NN-S2-UP1-RNNN motor?

The higher current capacity allows short-term overload handling. This provides stability during peak torque demands.

How does optical encoder technology contribute to positioning accuracy?

The optical system detects fine angular movements with high precision. This ensures accurate repeatability in positioning applications.
